本文探讨了在开发过程中遇到的JS布局错误，并详细解释了如何通过引入store来解决问题。文章强调了store在实现数据管理和状态管理中的关键作用，以及在避免布局混乱时的重要性。同时，提供了一个简单的示例来展示store的正确使用方法。 
	//fields end
    	InpatientViewPanel.superclass.constructor.call(this,{
    		region:"center",
    		height:400,
    		title:"医院住院病人信息",
    		viewConfig: {
    		        forceFit: true
    		},
    		//store:new Ext.data.Store({
    		//	fields:this.fields,
    		//	autoLoad:false,
    	//	//	url:"test.action"
    	//	}),
    		colModel:this.columnModel  
    	});

在之前只是想写一个页面暂时不写后台,但是这个时候出现一个错误this.ds is undefined,布局也是乱的,

后来才发现需要写一个store(注意上面注释的是在报错之前没有写) ,之后加上store后就OK了,随便写一个地址,autoLoad为false就好 了,

ExtJs中出现this.ds.fields.get(i) is undefined错误解决方法
02-25 3646
<br />出现问题如题:依旧谷歌得：<br />原因:在Grid的列定义中一定要指定dataIndex属性,即使没有store中的对应上(比如一些附加字段)也要指定一个dataIndex,否则就会出现this.ds.fields.get(i) is undefined的错误。<br />解决方法：当然就是补上列定义中的dataIndex属性咯..
javascript运行时错误:this.ds为空或不是对象

发生错误的原因是,配制参数名写错:                        var grid = new Ext.grid.GridPanel({                                                            renderTo:hello3,                                            
this.ds错误

出现了这样的错误 肯定是Store出现了问题 比如我们的fields和column里面的dataindex不一致  这样的问题都是我们平时如果仔细一点就可以避免的。 我曾经出现这个问题的原因是由于我在对Grid进行定义的时候，属性写成了一下这样： store : 'store'  不知道大家看没看出来 就是因为这对引号，所以一直报this.ds的错误。 贴出来 警示一下自己，希望对大家

但是，有些时候需要在前端先处理数据再传后端的时候就会出现这样的情况，因为有时候我们在处理数据的时候需要进行判断这个数组里面的变量是不是为空串或者未定义，之后满足条件之后达到我们想要的效果，但是在重置表单（data中定义的数组）的时候我们也习惯用 this . xxx = { } 来清空我们的表单，但是之后就会出现当前这个问题了。第二种：就是在开发项目的时候，通常都会将一些变量封装到数组中在data中定义方便我们使用，，就有必要用到 hasOwnProperty 方法，任何一个对象都具有该方法，它继承自。
